Frequently asked questions

Type the reading from your engine's hour meter into Vessly whenever you like, for example after a trip. Every hour-based task counts down from that number. There is no automatic reading from the engine.

No. Install and start. An account is only needed for Fleet, where several people share boats and changes sync between phones.

One currency per app, chosen in Settings. Prices on this site are in US dollars; store prices may vary by country.

Vessly puts maintenance, expenses, fuel log and PDF/CSV export in the free plan, works fully offline and does not require an account. YachtWave has more features for larger operations such as official logbooks and web sharing. See the comparison page for the full list.

Your data lives on your phone. You can export a full backup file and PDF or CSV reports at any time, on the Free plan too. Pro adds automatic backup to your own cloud account.

A backup file you export goes wherever you save it. With Pro, automatic backups go to your own cloud account; Vessly does not keep a copy on its own servers.

In the app go to Settings → Danger zone → Delete all data. After two confirmations it removes the data on your phone, your account and fleet memberships on the server and, if enabled, the Google Drive backup. Files you exported earlier are not touched, and a subscription is not cancelled by this — cancel it in the App Store or Google Play. See the privacy policy for details.

Yes. The Free plan covers up to three boats with maintenance tasks, engine-hour and calendar reminders, service history with photos and receipts, documents, checklists, inventory, logbook and PDF/CSV export. Pro adds expense analytics, the Boat CV PDF, cloud backup and a larger AI Mechanic allowance.

Paid plans start with a 14-day free trial. Cancel any time in your App Store or Google Play subscription settings; you keep access until the end of the period, and your data stays on your phone.

Fleet is priced per boat, from one boat up to fifty. Crew members join with an invite code and pay nothing; only the fleet owner pays.

The iOS app is in preparation for the App Store. It will have the same features as the Android app. Android is available on Google Play today.

English, Turkish, Dutch, German, French, Spanish, Italian, Norwegian, Portuguese (Brazil), Russian, Japanese, Korean and Simplified Chinese. The app follows your phone's language.

AI Mechanic needs an internet connection and has a monthly allowance: 15 messages on Free and 30 on Pro. It gives a first diagnosis based on your engine and service history; it does not replace a mechanic.
